Heating & Cooling

Materials: Cycle Time: Science vs. Rules of Thumb—Part 2
Understanding cooling—how a given material develops modulus as it solidifies—requires access to data that provides some insight into the relationship between modulus and temperature. Dynamic mechanical analysis is a helpful tool.

Leverage Your Cooling Power
You can predict the amount of heat you'll need to remove from parts before ejection with reasonable accuracy if you know polymer thermal properties and certain other rules of thumb.
